DISTRIBUTING HOOD.

Application filed May 28, 1925.

manufacture of resilient masses or bodies of fibrous material in theform of sheets, layers or batting, and especially adapted to be used in,the manufacture of the product known as wood cotton.

One method which has been employed in making wood cotton consists inseparating wood into a flocculent mass by shredding, and depositing theseparated fibers onto a belt or screen .conveyor so that they arrangethen'iselvesin a loose, resilient, heterogeneous mass. The fibers aretreated with an adhe sive either before they come in contact with theconveyor or immediately thereafter. Heretofore the fibers have beendeposited upon the conveyor by sifting them through one or more screensarranged at the bottom of a bin or receptacle into which the Wood fibersare continuously fed. This method of depositing the fibers upon theconveyor is not entirely satisfactory for the reason that the screenstends to become clogged and considerable time is wasted in cleaning thescreens and readjusting them. so that the operation can be continued.

The present invention provides means whereby loose material, such aswood fibers, can be deposited upon a traveling surface in an even layerwithout employing screens or other devices which readily become cloggedor disarranged. In general, I accomplish this result by providing asupply pipe through which the fibrous material is blown, and providing adistributing hood at the open end of the supply pipe. This hood isprovided with; an adjustable deflecting member arranged so that thefibrous material discharged from the supply pipe is deflected by thismember and distributed to any desired extent upon the surface of theconveyor.

The numerous advantages of my invention over the devices ordinarilyemployed for the purpose of depositing fibrous material upon a conveyor,will be apparent upon considering the following detailed description,which is to be taken in conjunction with the accompanying drawings, inwhich Figure 1 is a front elevation of my improved distributing hood anda section of a screen conveyor.

tributing hood and conveyor shown in Figure 1, and

Figure 3 is a fragmentary sectional view of certain details ofconstruction.

In Figures 1 and 2 I have illustrated a conveyor 1 of any common typesuch as the screen conveyors used in the manufacture of wood cotton orother resilient masses or bodies of fibrous material. Loose fibrousmaterial 2 is supplied to the conveyor 1 through a pipe 3 anddistributing hood 1. The pipe 3 may consist of any ordinary pipingthrough which fibrous material can be blown. The lower end of thissupply plpe is preferably bent into a horizontal posit-ion and the hoode is secured to this end of the supply pipe so as to extend down atsubstantially right angles thereto. The hood 1 preferably fan shaped, asillustrated in, Figures 1 and 2, and extends down into close proximityto the conveyor 1.

An adjustable deflecting member 6 is provided near the apex of the hood4: and is adapted to swing into the interior of this hood so as torestrict the passage leading downward from the supply pipe 3. Theprojecting end of the supply pipe 3 is closed by an abutment shown at 5,the opening in thispipe being provided at the bottom of the end thereof,facing downward into the hood a. The deflecting member 6, which ispreferably provided with a curved edge, is

hinged to the hood 1: at a point substantially in line with the openingin the supply pipe 3. An opening is provided in the side of the hood 4in the immediate vicinity of the hinged member 6 so as to accommodate anadjusting rod 7 by means of which the position of the deflecting membercan be changed. The deflecting member 6 can be hinged to the upper edgeof the opening provided in the side of the hood 6 and the adjustinglever 7 can be provided with teeth 8 adapted to engage the lower edge ofthis opening. The deflecting plate 6 can be locked in any desiredangular position by bringing the toothed lever 7 into contact with thelower edge of the opening in the details of construction, of mydistributing 7 device can be made Without departing from the scope. ofthe invention, which is not limited to the particular embodiment illustrated and described, but includes such modifications thereof as fallWithinthesoope of the appended-claims.

I cla m:

1. A, device ,of the type describectcom prising; a supplypipe, a distrbuting.hood

associated therewith, said hood having an opening-in the side thereof,and a rnernber having; a curved edge, said member being hinged to saidhood alongone edgeofthe opening inthe, side, th-ereofrand adapted to.swing into the interior thereof.

2A device of the type described comprising a supply pipe, a distributinghood.

,assoclated therewith, said hood having an opening in the side thereof,a deflectingv member having ,a curved, ed ge hinged to said.

hood along oneedge of. theopening in the side thereof and adapted toswng' into the interior thereof,,-and a toothed member icon-g nected, tothe free end fof' isaid deflecting member and arranged so that saiddeflecting nember canbe looked in any desired position by bringing thetoothed member into engagement with the edge of the opening" inthe sideof said hood.

' 3. A device of the type described comprising a supply p pe, a fanshaped d stributing hood associated there-with, said hood hav-f ing anopeningv in the side thereof, and adjustable .meansdassociatedv withsaid hood near saidopening for deter nining the distribution within saidhood of material supplied by said pipe.

i. A device of. the type described comprising a. supply pipe, a fanshaped distributing hood associated with the open end thereof and atright angles thereto, said hood having an opening in the side thereof,and adjustable means associated with said hood, near said opening ,for.regulating the velocityandrtlistribution of, material within said hood.

5. it device of the character described comprising a supply pipe, a fanshaped distributing hood fixed to the open end of said supply pipe andextending downward at substantially,right angles to this end of thesupply pipe, saidhoodhaving anopeningin the side thereof and near thetop thereof, a deflecting member -having a curved edge hinged tosaidhood along; one edge of the opening in the side thereof and adaptedto swing into the interior ofsaid hood, and a toothed member connectedto the free end of said deflectingniember and arranged so;;thatsaid-deflecting member can be locked in any desired position-by bringthetoothed member intoengagement with the, edge 'of the opening in the sideof said hood] 6. combination with a travelling surface and asupply pipe,a fanshaped distributing' hood associated with the open end thereof andat right angles thereto, and hav ing an adjustable, internal, deflectingplate so placed within saidhood near its intake throat as to regulatethe velocityand distribution of, material Withinthe said hood thatdischarge of the-material is effected in a layer of any. desired widthand thickness .upon said relatively travelling surface.

" 7. A device ofxthe typedescribed, comprising a supply pipe, adistributing hood associated with theopen endthereof, said hood havingan opening below and on the opposite side thereof to-thesupply pipeentrance, and aideflecting plate having one edge hinged to said hood=above said opening and adapted to swingeither into-deflecting positionwithin the hood ordnto coincidence with. the wall of thehood, therebyclosing said opening and-leavingthe interior of said hood free of allobstruction.
